PROBLEM TO BE SOLVED: To reduce the amount of back chorus data by generating the back choruses, in which same chorus phrases are repeated, from common data. SOLUTION: A musical sound reproducing type KARAOKE device 10 includes an LD changer system 11, a monitor 12, a mixing amplifier 13, microphones 14 and speakers 15. A KARAOKE control device 20 is called an integrated type system commander. By partially coupling the device 20 to the device 10, the entire system including the musical sound synthesis/musical sound reproducing functions is integrated and controlled. When musical sounds are generated using a sound source, a back chorus is beforehand digitally sampled and stored. During a reproducing, back choruses are repeatedly selected by the number of ADPCM data as back chorus envents and reproduced. Thus, the back chorus, in which same chorus phrases are repeated, is generated from common data. |
